minigbm: move camera work-around

Browse source 
Move mt8183_camera_quirk_ into struct cross_domain_private.
Add a helper `drv_get_os_option` in `drv_helper` to query os option.
Advertise DRM_FORMAT_MTISP_SXYZW10 as supported format in virtgpu_cross_domain.c.
Implement cross domain's own resolve_format_and_use_flags entry point.

BUG=b:269982880

TEST=tested on a kukui machine after applying the change. Camera and
screen recording works fine.
